[origin: ES8500382A1] 1. Moulded body in one piece made of mineral fibres provided with a binder for covering a perforated exhaust pipe in a sound-absorbing manner and particularly for fitting to exhaust silencers of motor vehicles, comprising at least one receiving opening for the exhaust pipe and at least one interface disposed inside the moulded body made of mineral fibres and formed from two juxtaposed surfaces of mineral fibre layers, the said moulded body (2, 2a, 2b, 2c) being formed as it were of several pieces of fibres, the mineral fibre layers of which (5, 6 5a, 6a, 9a 5b, 6b 5c, 6c, 9c) are connected to each other by means of the interfaces (7 7a, 10a, 11a 7b 7c, 10c, 11c), which are orientated in relation to the receiving opening (3, 3a, 3c) in a main direction which is esentially radial or parallel to this direction, characterised in that the layers of mineral fibres are gripped and secured with adhesive at the interfaces (7 7a, 10a, 11a 7b 7c, 10c, 11c).
